Subject: feat: ada_ls #3394

The configuration for the Ada Language Server was first added in #171 and
removed in #3310. The removal happened due to misunderstandings, it was thought
at the time that the default language server configuration could not work on its
own (#1683), it turns out that this was actually caused by a bug in the ALS that
was fixed a long time ago. This means the default ALS configuration can be
re-introduced.

However, in the meantime, a new neovim plugin for Ada was created and the name
"als" was borrowed, thus we have to use a new name, ada_ls, in order to avoid
breaking this plugin.

This reverts commit 7b8b0b3ddd0ed6eddc93982753acaddc578defac.
